  1. Well, I believe the glass is lot more permanent than acrylic (what I intended to install) so alternative way to observation is not quite necessary. Also a larger boat have more chance to provide full headroom under the dodger which make sense to extend it a bit further aft. I don't have full headroom under the boom either so the dodger is even lower. I've been on larger boat with hard dodger and I will never re-create the comfort what I experienced there (in terms of dodger height but of course it is true for the entire boat). I don't even try. 28" is really a funny size, probably the top of d
  2. Nope, not a problem, it actually helps IMO. But, for large, long windows, you need 2 or more people to make certain the windows are placed correctly and pressed into/onto the frames easily. Have plenty of rags and isopropal so you can clean up around the acrylic if you make a mess!
  3. I need to remove my cabin ports and replace the acrylic, and at the same time I need to do something about the aluminium frames as the are looking old and tired. Rather that parting about what I suspect would be big $$ to get the aluminium frames replaced new, I am wondering if getting them blasted by a professional outfit would have them looking like new? Anyone ever had this done themselves? And if so, how did it all turn out? Thanks in advance for any replies.
  4. .....The thickness of the tape is important. If you have long windows the expansion and contraction is quite high. It is best to create a "frit" with silicone based paint (Like exhaust paint) if the bond is exposed through the acrylic / poly-carbonate . Have a look at most modern cars , fixed windows and you will get the idea. This stops UV exposure on the tape / sealant interface. Mask all except the frit area, lightly abraid with 180, and spray. Goop by itself can work on fiberglass boats and smaller windows but is not a good idea on other materials and definitely not steel boats. Af
  5. Yep, Acrylic Creations | Acrylic fabrication specialists, Auckland for the windows, and QUILOSA MS35 from the Glue Guru on North Shore for the adhesive. You'll need to clean the frame with isopropol alcohol , both the ply side and the Acrylic side. The adhesive is strong and fast grab - easier if you can get someone to help you press them into the frames.
  6. Hi Rush - I deleted the UV strip. I was thinking for convenience (put it up Friday, drop it on Sunday evening....) I AM considering the elastomeric acrylic enamel paint trick as well, and Intend to test it on some similar fabric. example: Doyle also has a version: Do you guys have experience with these products?
  7. Another thing that sets panels apart is the clear covering. Cheap panels can use a clear acrylic, the better clear glass but even though it looks clear to our eyes, apparently not so to the Light Bugs. Apparently some just bounce off instead of through. You will usually see in specs of the more expensive panels, a figure that relates to light transmission through the covering. This goes hand in hand with the fact that many of the more expensive panels also work in a wider bandwidth of light and the two extreme ends of the light they can use tend to get reflected of the cover rather than transm
  8. Try Alternative Boat Windows. 021 536 366 They replaced a tempered glass window for me and did a nice job. They might do acrylic.
  9. You can get the windows off Keith from acrylic solutions. He's a boat owner too.

    deck paint

    ok time to paint decks,what to use?anyone had any luck with acrylic paints and special roller? want to go to a grey,as beige/deck cream never seems to stay clean.Going over the top of a grp deck that has anti skid patches.thanks
  11. get a paper chart either buy it laminated or get it laminated at somewhere like warehouse stationery Laminatingze A5 $1.79 A4 $2.99 A3 $3.99 A2 $7.99 A1 $14.99 https://www.warehousestationery.co.nz/print-copy/print-copy-services/binding-laminating then cut to shape and put under acrylic sheet http://www.mitre10.co.nz/shop/building_supplies/brackets_connectors/orca_panel_ace_acrylic_sheet_1200_x_600mm_clear_212883/
  12. The reason why I suggested Doming resin is that the surface does not easily scratch. Epoxy does. When I say scratch, it is minute surface scratching from just fingers and whatever you place on the table, and that dulls the surface over time. The Doming reason is more like Acrylic being scratch resistant. Norski here in Blenheim make it and I am pretty sure M10 stock the Norski products. Although it is a lot more expensive than buying from Norski I would expect. So you could try calling them or take a look and see if they have a website.
  13. Agree on the kiwi grip acrylic deck paint but the light grey that burnsco sells gets really hot underfoot. Because we've got so much cockpit floor area I get a tin of white and a tin of light grey and mix them together to lighten the colour. It still gets quite warm though but looks cleaner than using straight white.
  14. aren't they just a standard chart under a trimmed bit of acrylic? if not why couldn't they be?
  15. What product best to use to re bed a glass cabin window and deck prisms? The on the shelf sika products at chandleries are for acrylic windows and they told me to ring sika. Sika don't know what a deck prism is.

    Interior Paint?

    You can buy vinyl paint in spray cans from places like M10, supercheap and any autoparts shop. etc. Never tried using it myself. Enamels are harder wearing and more water impervious. Marine and "non marine" make little difference. But don't go cheap. There are some really cheap "home handyman" paints from likes of Bunnings and they are cheap to be cheap. You find the pigments are pathetic and you need 4 coats to equal the coverage of 1 of a decent quality paint. Acrylics are not so good at high wear and don't clean quite so easily. But it depends on where you are using it. One important thing
  17. Keith from Acrylic Creations, if he's not sailing around the country at the moment...
  18. Give Keith from Acrylic Creations a call. http://www.acryliccreations.co.nz/dt_gallery/boat-windows/ 098277118 He has done a couple of sets of windows for me. In fact my old boat 'Jagged Edge' features on the gallery page for boat windows. Keith owns the Alan Wright Marauder 'Manawa' and just did a circumnavigation of New Zealand. Great guy.
  19. Yeh - I just managed to break one of the tear drop windows while cleaning it and what I can't understand is why no one is answering my call into 0800-plasticmajicman at 2245 hrs on Friday the first of January! Just very poor service I have to say! I just hope the bugger can be bothered gettin in his Ferrari and driving back to Auckland from Bach Omaha to open the door on Monday morning! (F**k - anyone recommend a good acrylic window manufacturer?)

    Window tape.

    From Dow Corning: Q: Can Dow Corning silicone sealant/adhesives be used underwater? We do not recommend our silicone sealants/adhesives for continuous underwater use. Q: Will your sealants adhere to hard to bond to plastics such as polyethylene, polypropylene, urethane, acrylic or PTFE? Normally, no, silicone sealants generally will not adhere to these substrates; however utilizing one or more of the following adhesion improvement techniques (chemical treatment, roughing the surface, corona treating the surface) may help. Always keep in mind, that even though they may not have great adhes

    Chris is spot on. Sika or any of those adhesives, won't stick well to acrylic without the primer. Eventually they will let go and leak and if not mechanically held in, will come right out. Glass is a different story and MS and Silicons will adhere well.

    Window tape.

    It's good that you have a solution that works for you. I am a little reluctant to depart from Sika's recommended methods given the complexities of working with acrylic - I'm trusting them that it's not just money making advertising hype. Plus, I've already shelled out on all the expensive gunk. Two points: Cutting acrylic is pretty easy on a bench saw with a fine toothed blade if all you want is straight cuts. The majority of boat windows are curved and need a jig saw and the problem here is overheating of the blade which causes the acrylic to fuse back in the cut behind the blade. Edge chi
  23. Chewing Gum

    Window tape.

    No I our windows are actually quite large, would easily be bigger than a H28 and the sealant is very flexible. Not sure about the adhesion to Acrylic but I would be surprised if it didn't stick - would be easy to test it. It is not easy to remove the glass I can assure you.

    Window tape.

    There are two points Chewing Gum, firstly, your windows are glass, and secondly I would guess not too big, so the sealant you are using is very suitable. Acrylic on the other hand presents difficulties with adhesion, hence the need for Sika 209 primer which then needs the 295UV sealant for comparability reasons. Also, expansion and contraction of acrylic is huge compared to glass so it really needs a purpose designed tape/primer/sealant system at huge expense - unfortunately.

    Window tape.

    I couldn't say regarding your toe rails, but if you go to the 3M NZ site, you will find screeds of info as well as technical specs for all their products. I prefer tape/sikaflex fixing over mechanical fastening for acrylic. Tape provides even adhesion all around the perimeter of the window whereas mechanical fastenings create stress points - something acrylic doesn't like too much.
